doc: make rake linkchecker task and describe in readme
#2 Updated by Brett Smith over 7 years ago
Thanks for adding this. I love being able to do more tests locally—it means fewer bad builds on Jenkins. :)
The new h2 in README is numbered 2, duplicating the h2 after it. IMO we should just remove all the numbering.
As a general point of code hygiene, I think it'd be good to pass a block to Dir.chdir that does the linkchecker call. That avoids snagging future developers with the different working directory.
--ignore-url takes a regular expression. Could we better anchor the patterns that are meant to catch schemes, like
Is there any particular rhyme or reason to which external hosts are ignored? If it's supposed to be "all of them," I think it will save us maintenance time in the long run if we figure out a way to dynamically generate this list. I don't think it has to be perfect, just something that's good enough to avoid a requirement to add hostnames to the list when we add links. (I'm a little surprised and annoyed that linkchecker doesn't have a switch like --dont-visit-other-hosts, but them's the breaks.)
